File: README line 142
By jnoir:

"If this is failing, then when we initially created the user, it didn't set the smf_member_id in their options. We force/retain the smf_member_id on all options updates by making it a hidden forced setting."

Could you please elaborate on that? I am far from expert, and in my case that was the only way to make it work (see http://www.simplemachines.org/community/index.php?topic=467594.0 )
